Question

True or false?

Answer 1

FALSE.

The effect of adding +3 to the argument of a function f(x) is to shift the original f(x) horizoantally 3 units to the left.

Answer 2

Answer: This is false.

Step-by-step explanation:

The general function equation is,

$y=a\cdot \sin b(x+c)+d$

where,

period is $\dfrac{2\pi}{b}$,

horizontal shift or phase shift is c,

amplitude is a,

vertical shift is d.

The original equation of graph is, $y=4\sin (x)-2$

After shifting the equation of graph is, $y=4\sin (x+3)-2$

As per question, when we are adding 3 in original equation of graph then the graph shifted horizontally to the left by 3 units.
